Martin O'Neill's men were denied victory over the Hammers earlier in the season by a 93rd-minute Kevin Nolan goal, but Johnson is hopeful of avoiding a repeat performance.

“Their late equaliser earlier in the season was tough to take - it was the last kick of the game," he added.

“The lads were upset about it and it’s important to go out and put that right. However, it’s more important that we get the three points, but of course the win would be all the sweeter after the result down there.”

The 25-year-old has scored three goals and notched four assists since joining the club, but is keen to improve upon that in the coming months.

He continued: “Goals and assists are my game and I’d like to be getting amongst it a bit more, but it’s been difficult for the whole team.

“Hopefully I can contribute some more and have a hand in the goal that the team do score.

“I think the team can take confidence from the second half performance ahead of Saturday’s game, we need to build on our attacking play and put away the chances we create.

“Obviously it’s a different game but it’s going to be another physical test, but one we can hopefully take three points from.”
